Abstract: 1,059,481. Electrostatic transducers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. Jan. 22, 1964 [Jan. 25, 1963], No. 2799/64. Heading H4J. In an electrostatic transducer having a fixed electrode and a movable electrode formed by a vibratable diaphragm, the electrostatic driving forces applied to different areas of the vibratable diaphragm are graduated in order to ensure that the mode of vibration of the diaphragm corresponds with a single one of its natural modes despite change of frequency. The graduation may be effected, for example, by graduating dielectric constant, interelectrode distance, electrode area, bias voltage or driving voltage. The transducer may be a loud-speaker or microphone and all parts of the vibratable diaphragm may vibrate with the same phase, or the diaphragm may vibrate in stable nodal circles. In one arrangement (Fig. 3, not shown) the fixed electrode (2) has the form of concentric annuli which diminish in area from the centre outwards. Alternatively the fixed electrode may have perforations or be in the form of electroconductive mesh. Alternatively (Fig. 4, not shown) the fixed electrode (2) has a spherical surface whilst the movable electrode is planar. In a further arrangement (Fig. 5, not shown) the fixed electrode (2) has the form of concentric annuli, each of which is at a different potential. In another example (Fig. 6, not shown) the dielectric is in the form of concentric rings (51 to 56) of differing dielectric constant. The bias voltage may be supplied by a D.C. source (Fig. 2, not shown). Alternatively the fixed electrode may be of plastics such as a polycarbonate which is prepolarized at an elevated temperature. Since, with such material the charge leaks away, such fixed electrode may be charged periodically. In alternative arrangements the bias voltage may be obtained by rectification of a high-frequency signal (Fig. 7, not shown) or by one or both of pulse length and pulse height modulation (Fig. 8, not shown). For push-pull transducers full-wave rectification may be used. To obtain a substantially flat frequency characteristic the overall electrical impedance of the transducer may be matched to its mass. To assist in such matching the inductance of an output transformer may be utilized. Alternatively a feedback circuit may be used, the vibrational amplitudes of the movable electrode being detected by an auxiliary electrode (10) (Figs. 12, 13, not shown). In another arrangement (Fig. 14, not shown) high frequency power is amplitude- or phase-modulated by the variation of capacity between the fixed electrode (2) and movable electrode (1). Alternatively the oscillation frequency of a high-frequency oscillator is varied (Fig. 15, not shown). In another arrangement (Fig. 16, not shown) the movable electrode (1) has attached to it a piezoelectric element (20) which provides a feedback signal. Two flat electrostatic transducers may be placed adjacent and parallel to each other (Fig. 22, not shown) and connected to operate in opposite phase. Alternatively, a plurality of transducers may form a closed vibrating surface which vibrates as a whole.

Abstract: 1,225,645. Rolling. NARADI, NARODNI PODNIK. 3 July, 1968 [13 July, 1967], No. 31759/68. Heading B3M. A roller head for finishing an internal or external cylindrical surface includes a body 1 carrying a cage 5 in which a row of rollers 4 is mounted, the rollers co-operating with a cam 2 having a camming surface with an arcuate polygonal cross-section. A spring 8 and resilient pad 15 are located between the body and a rearward extension 5a of the cage. For finishing a bore, a tapered cam 2, Fig. 2, is employed, the cam being keyed to the body 1 and being axially adjustable relative to the rollers by an internally threaded ring 9. As the body 1 and the cam 2 are rotated the rollers 4 move radially over the cam surface. During axial feed of the body into the bore, the rollers are only able to move axially when they are between two protrusions on the cam. The spring 8 and pad 15 cause the rollers to be fed axially in steps at these times. A similar arrangement (Figs. 3 and 4, not shown) is provided for finishing the external surface of a rod, in this case the cam surrounding the rollers.

Abstract: 1,226,972. High-pressure apparatus. ROTARY PROFILE ANSTALT. 15 March, 1968 [17 March, 1967; 26 June, 1967 (2)], No. 12624/68. Heading B1X. [Also in Division C7] In a high-pressure cell, suitable for use in converting graphite into diamond, the material to be treated 1 (Fig. 2) is surrounded by particulate or ductile material 4 having a high degree of internal frictional resistance, such as sand or lead, which is compressed by forcing wedges 6 inwardly by rams 9 on which torque can be superimposed. Internal pressure is generated by electrical leads 16 connected to chemically reactive layer 3 which produces products which would be gaseous at normal temperatures and pressures. The function of material 4 is to dissipate pressure from the reaction zone outwardly by the effect of friction assisting the pressure-dissipating geometry of the cell. Ceramic segments 10 are arranged as shown in material 4. Envelope 12 contains high-pressure fluid 13 introduced through inlet 22. Heat may be removed from material 4 by cooling coils 15. A cell having a dumbbellshaped cross-section is also described. In Fig. 5, a metal rod is submitted to heat treatment by feeding it continuously through tube 102 which has deformable walls and is surrounded by a mass of particulate material 110 in casing 104. High-pressure is applied by means of wedges 112, 114, 116. Heat is applied by electrical means via wires 108 at diametrically opposite points for each series of wedges.

Abstract: 1,227,915. Charging batteries. McCULLOCH CORP. 29 April, 1969 [2 May, 1968], No. 21658/69. Addition to 1,219,324. Heading H2H. A method of charging a battery, such as a battery of sealed nickel-cadmium cells, comprises the steps of alternately charging the battery at a high rate and discharging it into a load, the signal controlling the change-over being derived as an integral of the terminal voltage of the battery. A circuit for charging a battery 1 comprises an A.C. source 12 rectified by diodes 6, 7 to produce a pulsating direct current by means of which the battery is charged by way of a normally closed contact 3 of a relay 14 and the bimetal element 27 of a thermal switch 25, the rate of charge being of the order of eight times the nominal one-hour rate of the battery. The battery voltage is sensed by means of a potential divider 17, 18, 19 and used to charge a capacitor 15 forming part of a relaxation oscillator 5. As the terminal voltage of the battery 1 increases, the charge acquired by the capacitor 15 increases until it reaches a value at which a thyristor 21 is gated on to energize the relay 14. Energization of relay 14 opens contact 3 to terminate the flow of charging current and closes contact 4 to connect the thermal switch 25 across the battery whereupon a high discharge current is taken from the battery. A contact 26 of the relay 14 also closes to discharge the capacitor 15 so that the gating signal for the thyristor 21 is removed. The relay 14 remains energized by virtue of a capacitor 23, the duration of the discharge period being determined by the size of this capacitor. After the relay 14 has dropped out and contacts 3, 4, 26 returned to the normal positions the charging and discharging cycle repeats, the frequency of the operation increasing as the battery terminal voltage increases. Charging of the battery is terminated when the battery voltage reaches a value at which the bimetal element 27 opens during a discharge period. This element is resettable manually. In a second embodiment, the relay is replaced by solid state components and the discharge circuit includes part of the transformer 9.
